Embodiment 1

[0047] First, lead alloy plates with a certain length, width and thickness are prepared by using lead plate production equipment.

[0048] Secondly, according to the battery size and capacity requirements, refer to Figure 1-Figure 6 As shown, the lead plate is processed into a continuous lead battery grid by using lead plate punching equipment. The number of coated areas of the grid is 6, located in the middle of the grid; the number of connecting areas is 5, located between the coated areas; the number of terminal areas is 1, located at one end of the grid.

Embodiment 2

[0050] First, according to the battery size and capacity requirements, refer to Figure 1-Figure 6 As shown, a continuous type lead battery grid mold was prepared.

[0051] Secondly, the molten lead liquid is injected into the mold by casting process to produce continuous lead battery grid. The number of coated areas of the grid is 2, located in the middle of the grid; the number of connecting areas is 1, located between the coated areas; the number of terminal areas is 2, located at both ends of the grid.

Embodiment 3

[0053] First, several pieces of monolithic grids are prepared.

[0054] Secondly, according to the battery size and capacity requirements, refer to Figure 1-Figure 6 As shown, a connection mold suitable for processing and connecting multiple grids is prepared.

[0055] Thirdly, put several single-piece grids into the connection mold, and inject molten lead liquid to make the multi-piece grids form continuous lead storage battery grids. The number of coated areas of the grid is 11, located in the middle of the grid; the number of connecting areas is 10, located between the coated areas; the number of terminal areas is 1, located at one end of the grid.

Abstract

The invention relates to the technical field of chemical power supply materials, in particular to a continuous lead-acid battery grid and a manufacturing method thereof, comprising a plurality of coating plate regions (2), wherein adjacent coating plate regions (2) are connected through connecting regions (3), one end or both ends of the grid are provided with terminal regions (1), and the coatingplate regions (2) and the connecting regions (3) are integrally formed. The continuous lead-acid battery grid adopts the integrated continuous design, which eliminates the welding process of multipleplates in the counter plate group of a single cell in the production process of the battery, and also eliminates the series-parallel welding process such as the cross-bridge welding and the through-wall welding between multiple cells of the battery. In this way, not only the lead consumption of the battery is reduced, but also the phenomena of chip dropping and welding leakage do not appear in the electrode plate group and between the cells of the battery, which effectively improves the product quality and reliability of the battery.

Description

technical field [0001] The invention belongs to the technical field of chemical power source materials, and relates to a continuous lead storage battery grid and a manufacturing method thereof. Background technique [0002] The existing lead-acid storage battery grid has a monolithic structure, and after the pole plates are made, multiple pole plates need to be welded. For batteries with multiple cells, cross-bridge welding and through-wall welding are also required. The above-mentioned welding method not only consumes a large amount of lead raw materials, but also is prone to problems such as chip drop and solder leakage. [0003] In view of this, we propose a continuous lead-acid battery grid. Contents of the invention [0004] The purpose of the present invention is to provide a continuous lead-acid storage battery grid to solve the problems of weak welding such as chipping and missing welding of battery plates in the background technology mentioned above. [0005] T...
